Thanks for the confirm Greg! Every part I've seen looks great so I expect nothing different inside the case...
This one is going under the grinder before I place it back in service! Those huge ports are just BEGGING for a performance build....
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
